Planning For a House Extension

When Planning A House Extension, There Are Several Factors To Consider, Such As:


One of the most critical factors to consider when planning a house extension is the budget. You need to set a budget that takes into account the extension cost of construction, installation, and any additional features you plan to add.

Planning permission

Check with your local authority to see if you need planning permission for your proposed extension. This will vary depending on where you live and the size and type of the extension you’re planning.

Existing structure

You need to consider the existing structure of your property, whether it’s a period property, grade II listed building, or a modern home. You need to make sure that the new extension complements the original architecture.


The design of your extension is crucial, and it should consider your existing property and the surrounding area. You may need to work with an architect or a designer to ensure that the new extension is cohesive with the original house.


The installation of the modern extension can also be a factor to consider, particularly if you’re planning a two-storey extension or a glass extension. You need to work with a reputable builder to ensure that the installation is done correctly.


Finally, timing is also essential when planning a home extension. You need to take into account the time it takes to design, obtain planning permission, and complete the construction, as well as any additional time required for installation and finishing.

Overall, there are several factors to consider when planning a house extension. With proper planning and the help of a professional, you can make this process easy. Whether is a ground floor extension, or rear extension, hiring a professional can help and save you time, money and stress!
